DELUXE Light package room heating 3, pipes insulated. Compact substation for drinking water systems and radiator heating utilising a countercurrent heat exchanger made of Cu/Ni brazed stainless steel. Central controller for hot water only operates as a pressure drop is detected when a hot tap is opened. Equipped with pre-fixed dp-controller 13 kPa with integrated zone control valve and thermal actuator for room temperature control. Assembly is available in surfacemounting or flushmounted versions. Pipe connection to an HIU is realised by means of a patented mounting system with pre-mounting unit. This unique installation system saves the installer the often complicated and time-consuming calibration and adjustment measures required on existing (pre-) installations. Ball valves can be connected optionally to the wall or to the floor.
